Biotic

Biotic factors are factors produced by living organisms that affect the ability of other living organisms to survive in an environment.

Some common biotic factors are disease, waste, parisitism, and predation. The overabundance of predators and lack of sufficient amounts of prey both are factors that hinder population growth.
